Heretofore, machines and apparatus have become known, by which the cleaning ofthe brass matrices for type setting and casting machines takes place in a more or less ad- -.I'vantageous manner. It is also known that such matrices are very sensitive and that high losses result from a bad treatment and cleaning of the same due to'the requirement of a repeated renewal thereof; On the other hand, a cleaning by hand is very time-wasting and thereby disturbs the normal work ing of the type setting and casting machines. The hitherto known cleaning machines possess the-drawback that their construction 16 is very cumbrous and sensitive and that they require a particularly careful attendance, treatment and cleaning, whereby the costs of manufacture and working of such machines arerathershigh. The present invention provides an improved cleaning machine of simple construction, through the cleaningcontrivances of i which the matrices to be cleaned can be automatically passed as often as desired; importance being however attached to the fact that the cleaning and polishing of the matrices is attained by passing the same twice through the machine, the matrices being cleaned at one broad side during the first passage and at the other broadside during the second passage through the machine, and correspondingly at its longitudinal edges.

The accompanying drawings illustrate a preferred constructional form of the improved machine:

and with certain parts thereof in different positi'on, to that shown in Fig. 1. To create a continuous automatic circulation of the matrices 5 (Figsf3 and 4) through the machine, that is, for. automatically returning the "matrices to the feeding channel,

the centrifugal "force'of the disc h designed for cleaning the broad sides of the matrices and rotating ini'the flyingdirection .ofthe latter, is used. Upon the matrices being freed from the locking rails g, they are caused to participatein' the rotary movement of the disc, from-which they arexlifted at an appropriate moment by the guiding rails '0 positions of the movable parts;

and projected, due'to the centrifugal force imparted'to them by the disc 71/, through the gabled return channel at, 0 into the vertical collecting channel a serving at the same time as feeding channel, for which purpose it is fitted with ahinged or detachable'cover 21 The guiding rails o are fixed to lateral guide-gplates of'the machine frame and located at. such a distance from one another that the disc k can just rotate between them. The

upper ends of said guiding .rails 11 adjoin the lower end of the flying channel n, o'and.

their lower ends embrace it (Figs. 1,2 and 16).- V

It is of importance that the disc h" consists of a plurality of layers of woven fabric for allowing the matrices to make sufficient,

part of the disc contact therewith for receiving therefrom the required centrifugal force. During their flying passage through the gabled return channel at, 0, the matrices are turned about their longitudinal axis, so that during their next passage through the machine their opposite broad side and longitudinal edges are cleaned. 'Said upside-down turning of the matrices, after each passage through the cleaning contrivances is effected by the downwardly directed branch 0 ofthe gabled return channel, which to this end consists of a brass pipe of oval cross-section which is twisted for 180 on its whole, length about its longitudinal axis. That part of the upwardly directed branch 71. of the gabled return channel adjacent to the rotary cleaning disc h is open at its lower end so that matrices, whichdo not attain the vertex m of the gabled return channel due to unsatisfactory rotary speed of the cleaning disc 72, and therefore fall back, can fall out of the gabled return channel after having slipped down the inclined plane formed-by the latter.

The principal cleaning of the broad sides of the matrices takes place underneath the cleaning disc h, and for thoroughly cleaning the same they must be locked for some time beneath the quickly rotating disc. This is attained by the locking rails 9 (Fig. 16)

consisting of two parallel narrowrails of tempered steel, which are riveted to one another at the distance of the breadth ofv a matrix and adapted to turn on a fulcrum Between said rails g the disc 'h is rotatably mounted. The left-hand end of said rails is inclined, while their right-hand end is hook-shaped by the provision of a recess 6 in the middle of each rail. To this end of the rails, besides, two draw-springs 1" are attached which tend to pull the hook continuously into its position of rest.

The locking and unlocking of the matrices byv the locking rails 9 takes place as follows:

The matrix supplied by the conveyor chain 7) lifts the locking rails g and is pushed by the tappets c of the chain onto the springy bridge 7 and thus'to the cleaning disc h. At this moment the locking rails 9 due to their lower recessed portions 6 slip off from the tappets and are pulled by the draw-springs rinto their position of rest. As soon as the matrix has arrived at the disc h, it is caught and liable to be driven alongby said disc.

To prevent this, the matrix is somewhat braked by a spring 1, so that the hook-shaped locking rails engage between the ears of the matrix and can lock the same during the cleaning process' If, then, the following chain tappet arrives with another matrix and lifts the locking rails g, the preceding matrix hitherto locked by the hook is liberated and projected by the fly-disc it back into the feeding channel a.

The succeeding matrix having effected the disengagement of the preof the matrices from the feed ranged on the left-hand sidewall of the feeding channel and adapted tobeadjusted in its position of height. Said angle-piece is so adjusted that the chain tappets 0 can always catch the lowermost matrix only, the

stepped arresting-spring t preventing the next superposed matrix from being advanced with the lowermost matrix. 2

The tappets 0 are arranged on both sides of the conveyor chain,'each two pairs of tappets belonging to each other andbeing connected, eachby two screws forming at the same time the chain bolts, with each other and with the chain (Figs. 5 and 6). The tappets lying in front, with reference to the direction of movement of the chain, serve'for support ing the'matrix only while the rear tappets serve as a support therefor with arear stop 'or abutment thereon. By this arrangement,

the matrices are reliably advanced and offered to the cleaning action, first by a brush 03 mounted to yield somewhat in upward direc-i.

tion, then by a sweeper e, and finally by the cleaning or polishing disc 7L serving at the same time as a fiy-disc as explained.

The brush (Z is suspended from the pivoted beam 7 (Fig. 1) by means of two screws 61 loosely passing through the latter and engaging in the back of the brush. Said screws carry coil springs d between said beam and said brush back for resiliently mounting the brush within the path of'the matrices in such a way that it comes in slight contact with the latter during their passage. underneath the brush. To meet wear of the brush bristles, it is simply necessary to correspondingly unscrew the screws (Z from the brush back.

The sweeper 6' (Figs. 7 and 8) comprises a rectangular thin blade-steel support clamped fast at itsends by means of two rails 8' and 9 screwed upon one another. Around said support and the upper rail 8 an endless cleaning ribbon of suitable fabric is turnably placed and held in stretched position by meansof a blade spring 11 fixed to the upper rail 8. Said sweeper is suspended from the beam 7 (Figs.

1 and 19) and located between the brush d.

. superposed benzine container 2 attached to the beam 7 delivers benzine to the ribbon.

Brush (Z and sweeper e are each enclosed by an open-ended casing (see Fig. 19). I

To allow an access to the path of the matv rices and to the upper part of'the endless conveyor chain 5 running therein, in the event of working disturbances, the brush. and sweeper are so arranged on the pivoted beam 7 that they can be easily turned-up and again turned-down by one manipulation (Fig. 19). For the same purpose, also the quickly rotating cleaning disc h, by which as mentioned the principal cleaning of the broad sides of the matrices is attained, can be turned-up from its position of use, said disc being further adjustably mounted by means of screws M (Fig. 16) to meet the natural wear of the same. Furthermore, the downwardly directed brancho of the gabled return channel is easily detachable, while the latter can be easily opened at its curves w, a? simply by turning its respective side walls upwards, the lat ter being hingedly aranged for this purpose (see dot-and-dash lines at w and w in Fig. 1)..

To create a reliable transmission from the chain-wheel y (Fig. 16) to the rail m or respectively to the springy bridge f carried by the latter, and acted upon in its middle by a corrugated spring 13 and at its top by a blade spring 14 whereby the disc 72; is resiliently held down in its operative position; the angle-piece s (Fig. 11) has,'at the left-hand side wall of the feeding channel a, a steel band 2 clamped thereto which extends to said springy bridge and is as broad as the chain 6 so that it lies between the chain tappets 0 and is kept in place by the latter. The fur ther guiding of the matrix into the gabled return channel takes place by the lateral guide-plates (Figs. 2 and 18), bythe disc h and springy bridge 7 (Fig. 16) I The latter is fixed on the rail Z, which is adjustably fastened on the rail m to provide adjustment for wear of the disc h.

The upwardly inclined part 1% of the gabled return channel 11, 0 is rectangular in cross-see. tion and consists at its upper part of a flatiron bar 3) and at its lower part of a U-shaped bar 9 fixed to the latter. A spring 15 (Fig. 16) is fixed to the lower end of the .bar p to prevent a hard striking of the matrices against said bar, while a spring 16 at the lower end of the bar 9 ensures a safe transmission from the guiding rails 12 to the channel n.

The .cleaning of the longitudinal edges of the matrices is effected by an emery strip 3 located on the inner side of the rear wall of the casing enclosing the'b'rush cl directly behind the latter, and by the rotatable felt disc 4 (Fig. 9). i The latter cleans the longitudinal edges ofthematrix between the ears of the same byengaging 'in{ a recess in the rear wall of the-feeding channel a. Both said contrivances 3 andt clean first one longitudin al edge of'the matrix and, after the latterbeing turned upside down, the other longitudinal edge of thesame.

What I claim, is:

' 1.- A machine for cleaning matrices for type setting and casting machines, comprising a'frame, a feeding channel at one end of said frame, means for cleaning the matrices including a rotatable disc at the other end of said frame, a conveyor to deliver matrices to said disc, to be cleaned, a gabled return dhannel for said matrices and guiding means to direct the matrices from the conveyor to the return channel, whereby said matrices upon being thrown by the centrifugal force of therotating disc, will travel through the return channel to the feeding channel. 7 q

2. In a machine as specified in claim 1, means in the downwardly directed branch of said gabled return channel for turning the matrices upside down during their passage therethrough.

3. A machine as specified in claim 1, in

which the upwardly directed branch of said gabled return channel is rectangular in crosssectlon.

8. In a machine as specified in claim 1, means for preventing insuificiently projected 4 matrices from obturating the path through said gabled return channel.

In testimony whereof I have hereunto set my hand.
